Short history: After independence in 1776 and a stronger federal government in 1787, the U.S. industrialized rapidly after the Civil War—between 1865 and 1898 coal output rose ~800% and rail mileage ~567%. By the mid-1880s it had surpassed Britain as the top producer of manufactured goods, and by 1900 it was the world’s largest economy. The two world wars then left Europe and Japan devastated while the U.S. economy nearly doubled (1939–1945), cementing the dollar’s reserve-currency status and its position as the global economic leader.

Note: “richest” depends on the measure—by total GDP the U.S. has been #1 since ~1890, but by GDP per capita it currently ranks around 10th (behind smaller nations like Liechtenstein and Singapore).
